Abstract: An electrical connector is shown which is mountable to a printed circuit board (200) which includes a plurality of insulating housings (4). A vertical row of terminals is formed as a subassembly (60) where the terminals (72 to 75) are integrally molded within an insert (82) of dielectric material. The lengths of the sections of the terminals (72 to 75) which are within the molded insert (82) vary to alter the impedance of the terminals (72 to 75), thereby matching the overall impedance of the terminals (72 to 75). Cross-talk shield members are insertable into the rear of each connector housing (4) to shield adjacent vertical rows of terminals from cross-talk. Upper (100) and lower shield members are insertable over the assembly to shield the assembly from EMI/RFI.

Abstract: An overheating protection triggering circuit for causing the switching-on of a guard transistor when a certain preset threshold temperature is reached employs a circuit for generating a reference current essentially proportional to a VBE/R1 where R1 is a preset resistance and a circuit formed by two complementary current mirrors, the first of which is emitter-degenerated by means of a preset resistance R2 in function of a certain area ratio (i.e. δVBE) of the mirror. The circuit basically performs a comparison between a reference current I1 = VBE/R1, strongly temperature dependent, imposed by the generator on the mirror circuit and a current I3 = δVBE/R2 relatively little dependent from temperature. With an increase of the temperature, the currents flowing in the two branches of the mirror circuit equal each other at a presettable threshold temperature thus causing the switching-on of a transistor. The temperature threshold is preset during the design by choosing a certain area ratio and a certain value for the resistance R2 of the first, emitter-degenerated current mirror and this temperature threshold is relatively insensitive to the normal spread of parameters.

Abstract: According to the present invention there is now available a cutting insert of sintered carbonitride alloy and with complicated geometry, said insert having improved efficiency. This is obtained by giving the powder non-­uniform compaction at the pressing so that the future working edges will have a higher relative density than surrounding, more "supporting" material in the pressbody. By these means are often obtained surface defects in the form of cracks because of dissolved strains during the sintering.

Each the sub-rate signals has a sub-rate which is equal to 1/N times a basic rate of the basic rate signal. A speech path memory (2) temporarily stores the digital multiplexed signal input to the sub-rate time switch. A channel signal is read out from the speech path memory and has a plurality of channels corresponding to time slots of the digital multiplexed signal. A control part (3-5) controls write and read operations of the speech path memory so that the channel signal includes N consecutive channels. Each of the N consecutive channels includes N identical sub-rate signals, and each of the N identical sub-rate signals corresponds to one of the N sub-rate signals included in the second time slot of the digital multiplexed signal.

Filed: 1991-02-26
Abstract: There are provided a method and an apparatus for manufacturing a cross-linked thermoplastic resin foam arranged as follows. A resin composition, which contains at least a thermoplastic resin, a foaming agent, and a cross-linking agent, is extruded into a closed die, which includes at least a molding region, a heating region, and a cooling region, continuously arranged in the order named. The resin composition is molded into a desired shape in the molding region of the die, and is then heated in the heating region to decompose the cross-linking agent and also to decompose at least part of the foaming agent so that cell nuclei are produced, thereby forming a partially foamed product. In the cooling region of the die, the partially foamed product is cooled to a temperature lower than the softening point thereof to be increased in rigidity, and is extruded to the outside of the die while being subjected to a damping force as it moves in the cooling region. The partially foamed product, extruded from the die, is heated under normal pressure to expand the foaming agent fully, whereupon a final product is obtained.

Abstract: A computer system package minimises latency between many high performance processors and a large amount of shared memory. Wire length, latency and skew are minimised while supporting a very fast cycle time and high bandwidth by stacking edge connected modules (ECMs), which are the basic building blocks. The ECMs 20 are characterised by signal input/output (I/O) pads on three edges, the two opposing edges being referred to as the inside connector edges and the third edge being referred to as the global connector edge. The ECMs support multiple processors per module, a plurality of basic storage modules (BSMs) per module, and portions of request and response switches per module. A plurality of processor ECMs and request switch ECMs are stacked in a first stack, and a plurality of BSM ECMs and response switch ECMs are stacked in a second stack. The two stacks are arranged adjacent one another with the request switch ECMs above the processor ECMs and the response switch ECMs below the BSM ECMs so that the response switch ECMs are adjacent the processor ECMs and the request ECMs are adjacent the BSM ECMs. The data flow from a processor to addressed memory and back to the processor is unidirectional about a loop defined by connections on the inside edges of the ECMs. The stacks form a subsystem which may be used as a stand-alone system or interconnected with other subsystems via the global connectors connected to the third edges of the ECMs. The global connectors allow the processors of one subsystem to be connected to the BSMs of another subsystem.

The reaction improves the yield and thermal stability of the lube range products. The olefinic oligomer mixture which is reacted with the aromatic compound is prepared from 1-alkene oligomerization in contact with a reduced metal oxide, preferably reduced chromium oxide, catalyst on support such as silica.
